Full Job Description

Safi’s mission is to make circular economy firms more profitable through the deployment of AI Technology. We do that by developing foundational models, software and data connectors. In this role you will deploy our technology with customers and help them use it to improve their plants. Why Safi? Our customers are industrial recyclers of plastic and metals - manufacturers, processors, smelters. These firms are held back by limited, legacy technology. Our current customers include one of the world’s largest recycling plants and a group that processes the entire plastic waste stream of a major developed nation. We have product-market fit and strong customer traction in an under-served market. We want to expand on that traction to help manage the entire end to end lifecycle of plants in multiple sectors. We’re backed by leading climate-focused VCs, including LowerCarbon Capital, Nosara Capital and Transition Ventures. If our mission resonates with you, we encourage you to apply, even if your experience doesn’t match every requirement. Who we’re looking for: We're at an early stage with a small team. We need an experienced Product Engineer to deeply understand these plants and help us automate and improve them. You: - Are excited about deploying technology at real-world industrial sites - Raise the product bar of strong engineers around you. Not via management, but via shipped work and the questions you ask in PRs and design reviews. - Can take a problem from "I saw something that could be improved at a plant” to a shipped feature in our app deploying at the plant, end-to-end, within a sprint or two - Can work closely with customers - assessing (not just blindly following) what they say, observing their operations and understanding what is the critical thing to impact - Are interested in commercial questions (how much do we charge for this?), deployment (what’s the right UI for forklift engineers wearing gloves?) and AI/ML (what can we build that is 10x better than their
